Question

我在matplotlib中有Tripcolor代码，我正在尝试使用Google Map作为背景来绘制此图像，但我正在使用gmaps库，但无法成功进行绘制。在gmaps中添加图层时，他们说poly实例必须是列表，然后我尝试将tripcolor输出为列表，然后这也无法正常工作。在将pp作为列表时，由于polycollection无法迭代，因此会出现其他一些错误。 Plzz让我知道了如何将我的Tripcolor与gmaps一起应用并成功绘制它。 TIA。我收到错误： TraitError：Polygon实例的“路径”特征必须是列表，但是指定了“ matplotlib.collections.PolyCollection”类的值（即）。

我希望三色图应重叠在Google地图上。背景应该是具有缩放功能的Google地图。
